Finger-tighten the three-jaw chuck onto a torque wrench or screwdriver, then twist either the gauge or tool to check the tool’s accuracy. A pointer on the dial shows torque as it’s measured—no batteries required. Bring these pocket-sized testers anywhere your tools are.

All testers come with a calibration certificate with test data traceable to either NIST or JIS, so they meet standards for accuracy. For the most accurate performance, the maximum torque you're applying should fall near the middle of the tester's torque range. Use with hand tools only.

Testers with memory pointer show the maximum torque reached.

Measure the torque output of torque wrenches, screwdrivers, and other hand tools to ensure they deliver the right amount of torque—and check your results on a digital screen. Cycle through four units of measure on the screen, then set it to display real-time or maximum torque. These testers have a keyless chuck that's similar to a standard drill chuck: insert the tool you're measuring and tighten the chuck by hand. They can also be used to measure the torque consistency of small rotating parts, such as motors, potentiometers, and encoders.

Note: For the most accurate performance, the maximum torque you apply should fall near the middle of the tester’s torque range.

Testers with calibration certificate with test data traceable to NIST include the test measurements that confirm accuracy.

The tester's memory keeps track of up to 999 different measurements. Use the USB cable and software download link (sold separately) to transmit, store, and analyze test data on a computer. The software stores time, date, and torque measurement values that you can import into Microsoft Excel.

To use the tester on external power, add an AC adapter (sold separately) and attach it with the USB cable (sold separately with the software).

For large and oddly shaped items, use a testing fixture (sold separately). Testing fixtures fit inside the tester's chuck and have four clamping pins that allow you to hold objects as wide as 2 1/4".

For handheld use, the display fits inside the back of the tester. To use the tester on a flat surface, remove the display from the back of the tester. For additional stability, mount the tester onto a testing stand (sold separately). Testing stands have four pins that fit inside the tester to anchor it, a handle for leverage, and mounting holes for permanently securing the stand.

Accurate to within ±1%, these torque testers are often used to check the accuracy of torque wrenches and screwdrivers on assembly lines. They come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. To test, place your torque wrench or screwdriver onto the tester with the included square drive connection and turn. These testers display torque as it's measured and the maximum torque reached. For accuracy when testing click-style wrenches, they also show the first torque peak reached. They’re not for use with impact or pulse tools.

Note: For the most accurate readings, the maximum torque you're applying should fall near the middle of the tester's torque range.

Bench-top testers can be mounted to your work surface. Those with a gooseneck display can be bent until you can clearly see the test results. Mount these testers to your workbench with a mounting bracket (sold separately). Or, carry them where they’re needed using the included case.

Monitor torque as you apply it—these testers mount between your torque tool and your fastener. Engage the fastener to track both torque and the angle of rotation for each crank of your tool (snug torque) before you've reached the final torque. This gives you a better idea if fasteners are consistently tightened than measuring torque alone. These testers are often used with nutrunners and click-style torque wrenches in the automotive and aerospace industries. Store up to 999 maximum torque (peak) and rotation values, including the date and time of each test, or transfer to your computer to view in an Excel file. CE marked, they meet European safety standards.

For the most accurate readings, the maximum torque you're applying should fall near the middle of the tester's torque range. They are not for use with impact tools.

Testers with a USB connection transfer data directly to your computer with the included cord. These testers last up to 10 hours on a single charge.

Testers with a Bluetooth connection wirelessly transmit data to a computer as you measure. You can also remotely set snug torque, or when these testers starting measuring the torque applied with each rotation. They last up to 8 hours on a single charge with Bluetooth on and 10 hours with it off.
